Hey guys. so i managed to get down to a ship that has a VAG tool today. We were able to connect to the car and make changes to the nav system but were were not able to connect to "77" to make changes to the BT module So i am guessing that mean i connected some wires incorrectly? (CAN wires?) Guess i need to rip out my seat and take a look. I double verified each wire when i did the switch... so i am a bit puzzled.
